> Majority in what way? Not necessarily a majority of the people.
The people are irrelevant, because the United States is composed of the States, not of the people. The majority of the states, through their electors, elect the President.
> So those states represent the views of more people. Under your system, someone in South Dakota would have a 1/750,000th of a say in their state's choice, while someone in California would have a 1/36Mth of a say in their state's choice.
Why care about the number of people represented? California is free to petition the Congress to split into smaller, South-Dakota-sized states if it so wishes. More to the point, California and South Dakota are individual sovereign states which are each part of the United States. They are constitutional equals. It would be unfair to give California forty-eight times the voice of South Dakota.
Frankly, I think our Constitution has a good balance: the People are represented in the House; the States in the Senate (which is why direct election of Senators is a catastrophically disastrous mistake); and states determine how to choose their electors. I'm in favour of constitutional amendments revoking the 17th Amendment and mandating that state legislatures appoint senators & electors.
